Hi Tinabeana,
I know how you feel trust me! Several of my "rescue" chinchillas come from pet stores.
Unfortunately they were also kept in poor conditions and not cared for properly. Usually we come home and I cannot stand it so we go back to get them.
I buy them and take them home with me to live a very nice life, like they deserve! I don't breed so no worry there.
These guys have turned out to be wonderful chins and very happy & appreciative ones! One is blind, and 2 have seizure disorders. Both of these medical problems have not been expensive or huge issues for us. If I could turn time back I'd do it all over again and adopt them again!
The pet stores all have gotten ear beatings from me on proper chinchilla care.
I have talked to them, taken in care sheets for them as well as their customers and introduced them to the chinchilla club site and others. I do have to say that many have improved the care since. So, it was all worth it.
I think they all run when they see me coming now!
